Abstract

A shroud (10) suitable for use in a gas turbine engine exhibits substantially uniform thermal growth. In one embodiment, a cooling system is arranged to provide impingement cooling of a leading portion (12) of the shroud (10). Cooling air is directed through holes (30) in a metal support ring (6). Other embodiments are also disclosed.
